Statement of Cash Flows: Sections, Methods, and Preparers

The statement of cash flows is one of the primary financial statements a company prepares each reporting period, and it organizes every cash transaction into three categories based on the business function that produced it: operating activities, investing activities, and financing activities. Unlike the income statement, which records revenue when earned and expenses when incurred regardless of whether money has changed hands, this statement tracks the actual movement of currency into and out of the business. That distinction matters. A company can report strong profits while running dangerously low on cash to cover payroll or debt payments, and the cash flow statement is what exposes that gap.

Why the Statement Exists

Accrual accounting, the system that governs most financial reporting, creates a timing mismatch between when a transaction hits the books and when cash actually moves. A company might recognize millions in revenue from contracts signed in December, but if customers don’t pay until March, the December income statement looks healthy while the bank account tells a different story. The cash flow statement corrects for that by showing what actually came in and went out during the period.

Investors and creditors use it to answer a straightforward question: can this company generate enough cash from its core business to keep operating without constantly borrowing or selling new stock? A company that consistently produces positive operating cash flow is funding itself internally. One that relies on financing activities to cover operating shortfalls is borrowing against its future. Spotting that pattern early is often more revealing than any earnings figure.

The statement also feeds free cash flow, a widely used metric the SEC treats as a non-GAAP financial measure. Free cash flow is typically calculated by subtracting capital expenditures from operating cash flow, and it approximates how much cash a company could direct toward dividends, debt reduction, or acquisitions after maintaining its asset base. The SEC requires companies that report free cash flow to describe how they calculate it and reconcile it with GAAP operating cash flow, since there is no single standardized definition.¹

What Counts as Cash

The statement doesn’t just track currency in a checking account. Under FASB’s standards, “cash” includes cash equivalents: short-term, highly liquid investments that are readily convertible to known amounts of cash and so close to maturity that interest rate changes pose virtually no risk to their value. The practical cutoff is an original maturity of three months or less.²

“Original maturity” is measured from the date the entity acquires the investment, not from the instrument’s issue date. A three-month Treasury bill qualifies. A three-year Treasury note bought when it has three months left also qualifies, because from the buyer’s perspective the maturity is three months. That same note would not have qualified as a cash equivalent when it was purchased three years earlier with a full term remaining.

Restricted cash and restricted cash equivalents also get folded into the totals. When a company holds cash that is legally or contractually restricted, such as funds set aside in escrow, those balances must be included in the beginning and ending cash figures. If the balance sheet breaks cash into multiple line items, the company provides a reconciliation showing how those line items add up to the total on the cash flow statement. Transfers between unrestricted and restricted cash aren’t treated as cash flow activities, since the money never left the company’s control.

Cash Flows From Operating Activities

Operating activities cover the core revenue-generating functions of the business and tend to draw the most scrutiny. Cash coming in from customers, interest received on loans, and dividends received on investments all land here. Cash going out to suppliers, employees, and tax authorities does too. Interest paid on debt is also classified as an operating outflow under U.S. GAAP, which sometimes surprises readers who assume it belongs with financing.

Direct Method vs. Indirect Method

Companies choose between two formats for this section. FASB encourages the direct method, which lists major categories of cash received and cash paid during the period: cash collected from customers, cash paid to suppliers, cash paid to employees. The result is a transparent, line-by-line view of where operating cash came from and where it went.³

Despite that encouragement, the vast majority of companies use the indirect method. This approach starts with net income and works backward, adjusting for items that affected reported income but didn’t involve cash. It is simpler to prepare because it draws on data companies already compile for their income statements and balance sheets, rather than requiring separate tracking of every cash receipt and payment. The investing and financing sections look the same regardless of which method a company uses for operating activities.

Indirect Method Adjustments

The most common adjustment is adding back depreciation and amortization. These expenses reduce net income, but no cash leaves the building when depreciation is recorded. Adding them back eliminates their drag on the cash total.

Gains and losses from selling long-term assets also require adjustment. If a company sells equipment for more than its book value, the gain inflates net income, but the cash from the sale belongs in investing. To avoid counting it twice, the gain is subtracted from net income in the operating section. Losses work in reverse: they’re added back because they reduced net income without representing an operating cash outflow.

Working Capital Changes

The final layer of adjustment involves changes in working capital accounts on the balance sheet. These reflect the timing gaps between when transactions are recorded and when cash moves.

An increase in accounts receivable means revenue was recorded but customers haven’t paid yet, so the increase is subtracted from net income.
An increase in inventory means the company spent cash stocking up before those costs hit the income statement, so it is subtracted.
An increase in accounts payable means the company received goods or services without paying the supplier yet, so the increase is added.
A decrease in current liabilities means bills were paid down, reducing cash, so it is subtracted.

After these adjustments, the bottom line of the operating section shows net cash provided by (or used in) operating activities. That single number is arguably the most important figure on the statement, because it reveals whether the business model itself generates cash or burns it.

Cash Flows From Investing Activities

Investing activities track cash spent on or received from long-term assets and investments. Common outflows include purchases of property, equipment, and machinery (capital expenditures), acquisitions of other businesses, and purchases of investment securities such as bonds or stocks issued by other entities. Common inflows include proceeds from selling those same types of assets, collecting principal on loans made to other parties, and cash from the sale of a business unit.³

Heavy outflows in this section often signal that a company is investing in future growth through new facilities, technology, or acquisitions. That isn’t inherently bad, but it does mean the company is consuming cash now with the expectation of returns later. Persistent negative investing cash flow funded entirely by operating cash flow is generally a sign of strength. Persistent negative investing cash flow funded by issuing debt or stock is a pattern worth watching carefully.

When a company buys another business, the total cash paid appears as a single investing outflow, net of any cash the acquired company had on hand at the time of purchase. After the acquisition closes, the two companies’ cash flows are combined into a single consolidated statement going forward. Costs directly related to the acquisition, such as advisory, legal, and accounting fees, take a different path: they’re expensed as incurred rather than capitalized, so they flow through the operating section.

Cash Flows From Financing Activities

Financing activities reflect how a company raises capital and returns it to the providers of that capital. Inflows come from issuing stock, selling bonds, or taking on new bank loans. Outflows include dividend payments, stock buybacks, and repayment of loan principal.³

A company that regularly generates more operating cash than it needs will typically show net outflows in the financing section, because it’s returning cash to investors through dividends and buybacks or paying down debt. A company that can’t fund itself internally will show net inflows here as it borrows or issues equity to fill the gap. Neither pattern is inherently good or bad without context, but the trend over several years tells a clear story about financial self-sufficiency.

Lease payments create a classification wrinkle. Under current FASB rules, operating lease payments flow entirely through the operating section. Finance leases are split: the interest portion of each payment is an operating outflow, while the principal portion goes into financing. Variable lease payments and short-term lease payments that aren’t included in the lease liability are classified as operating outflows regardless of lease type.

Non-Cash Investing and Financing Disclosures

Some significant transactions affect a company’s assets or liabilities without any cash changing hands during the period. Because no cash moves, they don’t appear in any of the three main sections. But they’re still important enough to require separate disclosure, either in a supplemental schedule attached to the cash flow statement or in the notes with a clear cross-reference.

Common examples include debt converted to equity (a creditor exchanges a loan for ownership shares, so the liability disappears and equity increases without cash moving); assets acquired by taking on a mortgage (a company buys a building financed directly by the seller, receiving an asset and a liability with no closing payment); right-of-use assets recognized on new finance leases; assets received as gifts; and non-cash exchanges of inventory, receivables, or other assets to settle liabilities.

When a transaction involves both a cash component and a non-cash component, the company reports the cash portion in the statement of cash flows and discloses the non-cash portion separately. The goal is to make sure readers see the full picture of how the company’s financial position changed, not just the changes that happened to involve cash.

Reading the Statement as a Whole

The bottom of the statement ties everything together. The net change in cash from all three sections, added to the beginning cash balance, must equal the ending cash balance shown on the balance sheet. If those numbers don’t match, something is wrong with the statement.

The relationship between the three sections reveals a company’s financial story more clearly than any single number. A mature, healthy company will commonly show positive operating cash flow, negative investing cash flow (because it’s maintaining and growing its asset base), and negative financing cash flow (because it’s returning cash to shareholders or paying down debt). A fast-growing startup might show negative operating cash flow, heavy investing outflows, and large financing inflows from venture capital or IPO proceeds. Neither pattern is automatically concerning, but a shift from one to the other over time signals a fundamental change in the business.

Who Has to Prepare One

Nearly all entities preparing GAAP financial statements must include a cash flow statement, and the accounting rules come from FASB Accounting Standards Codification Topic 230, which replaced the older Statement of Financial Accounting Standards No. 95.² For public companies, Section 13 of the Securities Exchange Act of 1934 requires periodic reports including annual and quarterly financial statements filed with the SEC,⁴ and SEC Regulation S-X requires audited cash flow statements for each of the three fiscal years preceding the most recent audited balance sheet.⁵ Under Sarbanes-Oxley Section 302, the CEO and CFO must personally certify that the filed statements fairly present the company’s financial condition.⁶

The statement of cash flows is designed to cut through the abstraction of accrual accounting and show what actually happened to a company’s cash. When analysts say they trust cash flow numbers more than earnings, this is the statement they’re reading.
